I did that but it can’t differentiate between replaced roof and overplating...

This seems obvious but I have heard of GRP being overplayed on the roof with steel inside the boat there are 2 metal wedges that I was told indicate that the roof was replaced (it’s a harborough) however there are a couple of leaks which come in under the gunnels which I was told might indicate fibreglass roof still want to sort some rust patches out in the summer but unsure what I’m dealing with anyone with a similar boat got any advice? thenk you

I’ll try and sort some pictures out

Yeah we measured the floorboard depth from an inspection hole up front to make sure we didn’t do a bad thing

Thanks for all the replies. Pretty certain the roof is steel despite the wedges, is it likely someone replaced the roof at some point? The engine sits outside the cabin space and is level with the floorboards. It’s a vetus I think the engine bilge is dry - where we drilled the holes were about 80cm apart along the length of the boat in the kitchen and steel below both. Should we drill below the back steps? That would be just in front of where the engine sits We have started to hear water sloshing about underneath our feet (not the canal!)

We know nothing about the history of our canal boat except it is a Harborough from the 80s. We desperately want to try and find blueprints which might help us. We think we have water under the cabin but trying to find a place to make inspection holes has resulted in us finding steel just below the floorboards stopping any further inroads The steel makes no sense to us though nor to a few people we’ve spoken to. Any ideas what it is and where we could try to drill a new hole? also half way down the boat in the cabin we have a steel ‘wedge’ either side under the gunnels directly opposite each other, is this normal? Is it an indication of the boat having been lengthened in the past?
